Re: Ricoh SC 544 Used reset fuse, Code comes back
What is the model? What have you done to repair the problem that caused the initial SC544. If is has not been properly repaired, the code will return. -
Re: Ricoh SC 544 Used reset fuse, Code comes back
Agree with Tim...What Model and what have you done?
If we're talking about a Cxx02/ Cxx03, etc., type machine, I don't bother with fuses, and use this jig instead (although I've installed a push switch on the end to release, instead of just crossing the wires). (Props to whoever posted this here years ago, including the push switch idea from another member!!)

I've also made the same for the smaller colour machine (C306/307, etc.) you just use a different connectorComment

I can't believe I forgot to put the model. Thanks for asking MP C4502. The new fix film came with busted heat lamp. I took the one out of a used one and used it. Thought I put itr back together right. Been having a tough time with this machine... Thanks again !!!Comment

Try SP3902-14Comment

Re: Ricoh SC 544 Used reset fuse, Code comes back
According to the service manual, you do not need to use a fuse to reset a Type A service code. You do have to cycle main power before going into SP mode then run SP 5810.1.
I had something similar once. A junior tech didn't know that the parts catalog he used had parts sections of all regions of the world and not just North America. Consequently he ordered the 200 volt unit for Japan and Europe. Since I was the only one in the shop when the part came in I got sent to the customer to replace it. Installed the new sleeve and it threw an under heat error. I had to change the heat lamps as the one being replaced was due to a torn film. Tear down was easy. Reassemble was another matter entirely.The new fix film came with busted heat lamp. I took the one out of a used one and used it. Thought I put itr back together right.

Re: Ricoh SC 544 Used reset fuse, Code comes back
Forgot to mention, since the SC is for overheating, check the connection and condition of the thermistors. One could be either bad, disconnected or have a pinched lead.Comment

Re: Ricoh SC 544 Used reset fuse, Code comes back
Important: The fusing unit cannot be used because an abnormal high
temperature was detected.
After this SC occurs, the counter reset of the fusing unit should be done
manually using SP3-902-014 because the counter reset is not done
automaticallyComment

Re: Ricoh SC 544 Used reset fuse, Code comes back
But that is only for new fusing unit set. It will clear the fusing unit PM due message. That was added to the service manual because clearing the fusing unit PM counter with this model does not clear the message. The original service manual did not have it. Also it does not clear the PM counter. SP 7624-015 must be run to clear that.
It does not clear the service code.Comment

Re: Ricoh SC 544 Used reset fuse, Code comes back
as the sleeve havent sensors, I have either broken the liner sleeve, or is electrically interrupted (which cannot create overheating)
I would focus on the sensors, clean / replace the thermistors, in particular the sensors with the yellow windows, with diluent and cotton swabs, they gave me a problem a few days ago, and I solved this, instead for the fuses, do as they suggested to you, or as I always did in that discussion

Re: Ricoh SC 544 Used reset fuse, Code comes back
He has said that this is a MP C4502. Only has contact thermistors. When removing and reinstalling the bottom cover of the fusing unit you have to follow the service manual exactly or risk damaging the thermistor leads.as the sleeve havent sensors, I have either broken the liner sleeve, or is electrically interrupted (which cannot create overheating)

Re: Ricoh SC 544 Used reset fuse, Code comes back
I hope I have understood your problem well.
if you install the lamps of a mpc 3502, it will give you this error sc 544.
the connectors for mpc4502 and mpc 5502 are yellow, all three, while for mpc 3002 and 3502 all three are white.
maybe that's it.Comment

hi, I thought I dreamed it, or checked on the wrong manual, but I looked again, and there are those sensors, are the item 27 and 28.D143_D144_EU_V1.11_fuser section 1.pdf"loneliness is an invention of the white man, when we are alone we talk to everything around us, we are never alone" (Ojibwa)Comment
